There are a lot of people here posting that the Ribbon is a bad design, and I agree with them 110%. But that's not the only thing that's wrong with Word: it also distributes controls all around the edges, and unless you use it day in and day out, and use those distributed controls, it's a pain finding them.
Unfortunately, LibreOffice has copied this bad UI from Microsoft. I'm looking at LO Writer now, and in addition to the menu at the top, there's a sidebar on the right with eight or ten indecipherable icons (one of which looks like a hamburger menu, except it isn't). There's a Find box near the bottom with its controls. And on the status bar, there's a zoom (I think) gizmo on the right, something that looks like pages with folded-over corners next to that, a few more boxes or something, a page style chooser(?), and an image of a 3 1/2" floppy diskette on the left. I think I can get rid of all this cruft, but why is it there in the first place? I certainly don't use most of those things very often (except search, for which ^F works fine, thank you!), and they just waste space.
